Flow batteries – more akin to fuel cells, really – are getting increasing attention as researchers press to meet a need for energy storage brought on by the rise of intermittent renewable sources like solar and wind.
It doesn't take a Watson to realize that even the world's best supercomputers are staggeringly inefficient and energy-intensive machines. Our brains have upwards of 86 billion neurons, connected by synapses that not only complete myriad logic circuits; they continuously adapt to stimuli, strengthening some connections while weakening others.
Half the size of a paperclip, weighing less than a tenth of a gram, it leaps a few inches, hovers for a moment on fragile, flapping wings, and then speeds along a preset route through the air.
Researchers at Harvard University recently showcased a very interesting project where a human participant managed to control a rat.
The Earth's only been this warm for about a quarter of the time over the last 11,300 years, a new reconstruction of the planet's temperature history shows.
Humans have at least two functional networks in their cerebral cortex that aren't found in rhesus monkeys, and which appear to be unique.
A single mutation around 30,000 years ago appears to be responsible for several traits common in East Asian peoples, from thicker hair to denser sweat glands.
Harvard researchers are currently devleoping "soft robots" that are capable of performing all sorts of functions robots made out of rigid materials, such as metal, are unable to do.
'Black-sounding' names are more likely to trigger ads associated with criminality, says a Harvard professor, in what could be Google's racism - or everybody else's.
Solar geoengineering can be safely tailored to manage specific risks like the loss of Arctic sea ice, says a group of researchers keen to persuade the world that such techniques aren't necessarily a disaster waiting to happen.
It's long been theorized that the moon was created when a Mars-sized proto-planet slammed into the Earth. Unfortunately, though, the chemistry of the two bodies has stubbornly failed to bear this out.
Humans last interbred with Neanderthals well after they spread out of Africa, a genetic analysis has shown.
New evidence has emerged that Jesus was married - or, at any rate, that some early Christians thought he was.
A new, ultra-thin flat lens has a focusing power at the very edge of what's theoretically possible, promising a distortion-free image.
Harvard scientists have, for the first time, merged human tissue with a network of bio-compatible nanoscale wires to create 'cyborg tissue'.
It may not be grand enough of a topic for Al Gore, but Harvard is interested in seeing how climate change affects butterflies.
To demonstrate that DNA's suitable for use as a large-scale data storage medium, a team of scientists has encoded a 5.27MB book using DNA microchips, and then read it back again.
Harvard researchers have developed a soft-bodied robot, based on a starfish, that can camouflage itself when required - or color itself brightly.
Thunderstorms are punching new holes in the ozone layer over the US, say Harvard University scientists.
Scientists have created a free-swimming 'jellyfish' out of silicone seeded with living heart muscle cells.
